Abstract
For sealing of higher pressure at a rotating shaft conventional elastomeric- or PTFE-seals can only be applied at low sliding velocity. Up to now a mechanical seal was the only possibility of reliably sealing a pressure up to 3 MPa at a sliding velocity of 5… 10 m/s. This paper presents a new, pressure-balanced shaft seal called “Entlasteter Wellendichtring (EWDR)” /1/, which has been proved to correctly operate in laboratory tests at pressure up to 3 MPa and surface speed up to 12 m/s.
